On the 30th, the day of the riot, and after it was suppressed, General Baird wrote to Mr. Stanton a long letter, from which I make the following extract:

SIR: I have the honor to inform you that a very serious riot has occurred here to-day. I had not been applied to by the convention for protection, but the lieutenant-governor and the mayor had freely consulted with me, and I was so fully convinced that it was so strongly the intent of the city authorities to preserve the peace, in order to prevent military interference, that I did not regard an outbreak as a thing to be apprehended. The lieutenant-governor had assured me that even if a writ of arrest was issued by the court the sheriff would not attempt to serve it without my permission, and for to-day they designed to suspend it. I inclose herewith copies of my correspondence with the mayor and of a dispatch which the lieutenant-governor claims to have received from the President. I regret that no reply to my dispatch to you of Saturday has yet reached me. General Sheridan is still absent in Texas.

The dispatch of General Baird of the 28th asks for immediate instructions, and his letter of the 30th, after detailing the terrible riot which had just happened, ends with the expression of regret that the instructions which he asked for were not sent. It is not the fault or the error or the omission of the President that this military commander was left without instructions; but for all omissions, for all errors, for all failures to instruct when instruction might have averted this calamity, the President was openly and persistently held responsible. Instantly, without waiting for proof, the delinquency of the President was heralded in every form of utterance. Mr. Stanton knew then that the President was not responsible for this delinquency. The exculpation was in his power, but it was not given by him to the public, and only to the President in obedience to a requisition for all the dispatches.

No one regrets more than myself that General Baird's request was not brought to my notice. It is clear from his dispatch and letter that if the Secretary of War had given him proper instructions the riot which arose on the assembling of the convention would have been averted.

There may be those ready to say that I would have given no instructions even if the dispatch had reached me in time, but all must admit that I ought to have had the opportunity.

The following is the testimony given by Mr. Stanton before the impeachment investigation committee as to this dispatch:

Q. Referring to the dispatch of the 28th of July by General Baird, I ask you whether that dispatch on its receipt was communicated?

A. I received that dispatch on Sunday forenoon. I examined it carefully, and considered the question presented. I did not see that I could give any instructions different from the line of action which General Baird proposed, and made no answer to the dispatch.

Q. I see it stated that this was received at 10.20 p.m. Was that the hour at which it was received by you?

A. That is the date of its reception in the telegraph office Saturday night. I received it on Sunday forenoon at my residence. A copy of the dispatch was furnished to the President several days afterwards, along with all the other dispatches and communications on that subject, but it was not furnished by me before that time. I suppose it may have been ten or fifteen days afterwards.
